摘要
本文根据长距离压力输水系统和多点布置进排气阀的特点,结合当量管道法和调整波速法,建立了水锤计算中的自动分段方法,同时将其用于进排气阀的水锤过程计算中.通过建立的进排气阀计算模型在实例中的应用和计算分析,不仅确立了计算方法的合理性和易用性,而且提出了进排气阀在工程应用中有着实际意义的结论.
The auto dividing method of the pipeline is proposed in this paper which it combines the adjusted method of the pressure wave speed and equivalent method of pipeline.A calculation model is built in which the air inlet and vent valve and the auto dividing method are used.The application of this model shows that the rational adoption of air inlet and vent valve is significant.
